3M™ Scotchlok™ Connectors and Tools

50 years ago, 3M introduced the industry’s original insulation

displacement connector—the 3M™ Scotchlok™ Connector UR. Today,

with increased demand for high-speed and high-bandwidth networks,

the complete series of 3M connectors and tools has evolved again. We’ve

leveraged new technologies while building on the original successful

design, shape, color-coded cap concepts and element conﬁguration. With

the Scotchlok series of tools and connectors from 3M, service providers

can meet the demand for enhanced customer services such as high speed

internet, video-on-demand and video conferencing. 3M™ Scotchlok™

Connectors additionally offer full wire-range capability, increased port

size to accommodate up to 2.08 mm (0.082 in.) insulation sizes, double

elements in all products and solvent resistant plastic construction.

As new technologies migrate into the local loop, the importance of

reliable connections in the embedded plant has increased exponentially.

Each connection is a potential point of failure in high-bandwidth

applications which could require additional time and expense for a

technician to repair. That is where the full line of 3M™ Scotchlok™

Connectors really makes a difference.

3M™ Scotchlok™ Butt Connector UAL

The UAL connector is a sealed, moisture-resistant two- or three-wire connector. Outside ports

accept solid-copper, aluminum, or a combination of both. RUS Listed.

3M™ Scotchlok™ Butt Connectors

Scotchlok butt connectors employ a specially designed, wire insulation displacement contact to make a reliable electrical

connection to each wire. A “live-spring” joint is made by driving the wire down into the “U” contact connector. This simple

process displaces the insulation and grasps all conductors with a ﬁrm, resilient pressure, all in one motion. No stripping of

wire insulation required. Scotchlok butt connectors include a factory-installed sealant to protect against corrosion and seal

out moisture. They are also available in a dry/ﬂame retardant version for central ofﬁce and vault. A variety of sizes and wire

combinations are available to accommodate almost any need.

3M™ Scotchlok™ Butt Connector UYF (OUS only)

The UYF connector employs a specially designed insulation displacement contact which makes

an electrical connection to each wire. The connector is ﬁlled with a sealant to provide moisture

resistance. The small size of the UYF connector reduces the splicing bundle O.D. to a minimum.

3M™ Scotchlok™ Butt Connector UP2

The UP2 connector is a dry, ﬂame-retardant two-wire UL-Listed connector for use on paper,

pulp or PIC cable where moisture resistance is not needed. RUS Listed.

feature for use on pulp, paper or PIC cable where moisture resistance is not needed. RUS Listed.

3M™ Scotchlok™ Tap Connector UB2A/UB2A-D

The UB2A/UB2A-D connectors have a pre-crimp feature that gives the craftsperson a

time-saving edge. By positioning the connector on the conductor and pre-crimping, the

conductor is prevented from slipping out of the connector before the crimp is completed.

A factory sealant protects against corrosion and seals out moisture. In ready-access closures,

these connectors help eliminate cutting cable pairs, opening circuits, and piecing out wires. The

UB2A-D connector is a dry version of the UB2A. RUS Listed.

3M™ Scotchlok™ Tap Connectors

Scotchlok tap connectors are real time savers. They enable the user to tap into another wire without interrupting service.

A U-shaped element inside each connector displaces insulation material and makes contact with the copper conductor.

Scotchlok tap connectors also include factory-installed sealant to protect against corrosion and seal out moisture. They are

also available in a dry version for central ofﬁce and vault. Scotchlok tap connectors are fast to install, easy to work with and

available in a wide range of common wire gauges. Tap connectors allow direct tapping into existing solid copper conductors

without interrupting service. The pre-crimp feature helps hold the wires in place until the connector is crimped and the

splice is complete.
